Each of the sections 1 and 2 is provided A still further object of my invention is with channels or recesses 12 which register 40 to provide a heater or boiler which will be with each other as clearly shown in Figs. 3 of comparatively compact construction and and 1-.

One Figure l is a front elevation of a boiler of said hollow extensions of each of the secor heater made in accordance with my intions 1 and 2 is shorter than the others and 50 vention. centrally located so that when the sections atria are placed together as shown in Fig. 4, a space will be provided between them for a purpose hereinafter described, while the other of said hollow extensions of each section respectively contact with each other.

It will, of course, be understood that each of the sections 1 and '2 are hollow and may be filled or partially filled with water which will become heated by the passage of the products of combustion upwardly through the fiues provided by the channels 12.

I preferably secure the sections 1 and 2 together with right and left hand threaded nipples 15 and 16, the opposite ends of the nipples fit within tapped openings in said central hollow extensions, each of said nipples being provided with hexagonal nuts intermediate their ends which are located within the space provided by the oppositely disposed central hollow sections, so that the turning of said nuts will tend to draw the sections 1 and 2 together and securely hold them in position.

. Each ofthe sections 1 and 2 is provided with an overlapping lip 17 which forms a closure adjacent the outer edges for the parting which exists between the sections 1 and 2. It will thus be understood that each of the nipples 15 and 16 forms a con-- pling for the sections and also forms a means of communication between the interior of said sections as clearly shown in Fig. 2.

heater or boiler constructechin accordance with my invention can beeasily manufactured and assembled, is eiiicient in service, and is durable.

In the modification shown in Fig. 5, I have shown the boiler sections 18 and 19 half elliptical in cross section and joined to form an elliptical boiler. With the exception of the shape of these sections, the construction is similar to that described in connection with Figs. 1 to 4 inclusive and I have therefore given like parts similar reference numerals.

In Fig. 6, instead of having the lips 17 forming the seal at the outer edges, I pro vide a tongue and groove connection as shown at 20 to form a seal joint, and it will be noted that if desired the joint connection between the lips 17 and the adjacent sections maybe calked or plastered prior to the joining together of said sections so as to form a perfect seal. In a similar manner, plaster or other sealing material may be provided in addition to the tongue and groove connection as shown at 20 in Fig. 6. While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but
